Several times a year the ARISS (Amateur Radio on the International Space Station) team is setting up SSTV (Slow Scan Television) events where images are transmitted from the ISS down to earth. The SSTV signal can be received with a conventional hand held radio…
Portable ham radio operation require a portable energy source, e.g. a rechargeable battery. Usually lithium based batteries are chosen because they store a lot of energy while at very low weight. However, there are different types of lithium based batteries…

As outlined in my first post I simply love to operate battery powered in the great outdoors. Therefore it’s only natural to participate in the SOTA (Summits-On-The-Air) award program which requires setting up portable ham radio stations on the top…
The Yaesu FT-817ND is a little and versatile all-band multi-mode portable ham radio transceiver which I am using routinely during SOTA (Summits-On-The-Air) activations. Although the little radio is already quite capable in it’s default configuration there are several tuning options…
